5G NR Unlicensed Channel Detection for Large-Bandwidth Load Adaptation

The patent divides the large bandwidth channel into multiple sub-channels or frequency segments for parallel detection. Instead of detecting the entire 400 MHz bandwidth as a single unit, the channel detection process is segmented into smaller frequency ranges that can be processed independently and in parallel, reducing the computational complexity while maintaining detection accuracy.

The patent introduces dynamic channel detection mechanisms where detection parameters such as bandwidth, detection timing, and detection granularity are adjusted based on current channel conditions, traffic load, and service requirements. This dynamic adaptation allows the system to reduce processing complexity under light load while maintaining high detection accuracy when needed.

The patent implements dynamic bandwidth adaptation where the channel detection bandwidth is flexibly adjusted based on actual service requirements and channel conditions. For small bandwidth requests, detection is performed on a reduced bandwidth subset, while for large bandwidth requests, full bandwidth detection is activated. This dynamic approach significantly improves resource utilization efficiency while maintaining channel access reliability.

The patent changes key detection parameters such as detection bandwidth, detection power threshold, and detection timing based on channel conditions and service types. By dynamically adjusting these parameters, the system optimizes the balance between channel access reliability and resource utilization efficiency, avoiding unnecessary full-bandwidth detections when not required.

The patent segments the 400 MHz bandwidth into multiple detection regions or frequency sub-bands. Instead of continuously monitoring the entire bandwidth, the system performs detection on selected segments based on scheduling requirements and channel conditions, significantly reducing power consumption while maintaining essential channel information completeness through selective monitoring.

The patent implements periodic channel detection with variable intervals rather than continuous full-bandwidth detection. Detection is performed periodically at optimized intervals, and the detection bandwidth is adjusted based on channel activity patterns, allowing the system to reduce power consumption during idle periods while maintaining channel information completeness when traffic is active.
